In order to hold the securing plates B in position during erection ofthe panel, rubber or similar bands d may secure them resiliently orotherwise to the web a of the strip A. The presence of these bands afterthe boards or panels have been secured is not detrimental but usuallybeing of a light nature and under tension they will break either duringthe securing of the plates by the screws or not long after.

The securing plates B may be made of metal or any other suitablematerial and be of any desired shape according to the use of which theyare required.

When it is desire-d to secure one section strip A at right angles toanother to form a cross member the flanges a of the strips forming thecross member are cut away at the ends a as shown in Fig. 9, so that thebottom of the web a of the cross member will rest on the flanges (1. ofthe other member.

To secure the ends of two section strips A togcther a horizontal slit ais formed-in each of the abutting ends of the webs a and a fish plate Aof channel section of a length equal to that of the two slits (1 seeFig. 9, is inserted into the slots so that when the two ends are broughttogether as shown in Fig. 10, they are firmly secured by the fishplates. The channel in the fish plate A is of approximately the samewidth as the thickness of the webs-L of the strips A, the thickness ofthe horizontal member of the fish plate is approximately equal to thedepth of the slits a and the depth of the side members of the fish plateis preferably such that the lower edges are in contact with the surfacesof the flanges a For using the section strip A as an inside ridge finisha plate B with slotted inclined ends I) as shown in Fig. 7 may beemployed. The plate Bi fits into one of the slots at in the strip A andthe slots in the ends of the plate fit over the web of the inclinedtransverse strips.

To secure the section strip A to a purlin a bracket e is aflixed to theweb a of the strip as shown in Figsli) and 11 and the strip is suspendedfrom the purlin E by this bracket.

A similar method as shown in Figs. 12 and 13 is employed for attaching asection strip or strips A at the sides of a truss F, a bracket f beingriveted or otherwise secured to the web a of the strip and the stripsuspended from the beam or purlin F to which the truss F is secured.

The section strip may be made of metal, synthetic'resin or other plasticmaterial or it may be built up of laminated paper, wood or othersuitable material.

What I claim as my invention and desire to protect by Letters Patent is:

1. Means for securing Wallboards, ceiling boards, panelsand the like inposition comprising in combination a T shaped section strip with curingthe said edge between the plate and the a perpendicular slot formed inthe web member thereof, a securing plate extending through said slot andadjusting means passing through the flange of the section strip from theface thereof and engaging said plate for the purpose of drawing thelatter on to the rear surface of the edge of the board and securing thesaid edge between the plate and the flange.

2. Means for securing wallboards, ceiling boards, panels and the like inposition comprising in combination a T shaped section strip with aperpendicular slot formed in the web member thereof, a securing plateextending through said slot and a screw passing through the flange ofthe section strip from the face thereof and into a tapped hole in thesecuring plate for the purpose of drawing the latter on to the rearsurface of the edge of the board and securing the said edge between theplate and the flange.

3. Means for securing wallboards, ceiling boards, panels and the like inposition comprising in combination a T shaped section strip with aperpendicular slot formed in the web member thereof, a securing plateextending through said slot, the securing plate being wider than theslot and formed with a recess at each side to embrace the edges of theslot and a screw passing through the flange of the section strip fromthe face thereof and into a tapped hole in the securing plate for thepurpose of drawing the latter on to the rear surface of the edge of theboard and securing the said edge between the plate and the flange.

4. Means for securing wallboards, ceiling boards, panels and the like inposition comprising in combination a T shaped section strip with aperpendicular slot formed in the web member thereof and a horizontalslit in an end of the web, a securing plate extending through the saidperpendicular slot, adjusting means passing through the flange of thesection strip from the face and engaging said securing plate thereof forthe purpose of drawing the latter on to the rear surface of the edge ofthe board and securing the said edge between the plate and the flangeand means co-acting with the horizontal slit in the Web to join onesection strip to another.

5. Means for securing wallboards, ceiling boards, panels and the like inposition comprising in combination a T shaped section strip with aperpendicular slot formed in the web member thereof and a horizontalslit in an end of the Web, a securing plate extending through the saidperpendicular slot, adjusting means passing through the flange of thesection strip from the face thereof and engaging said securing plate forthe purpose of drawing the securing plate on to the rear surface of theedge of the board and sefiange and a channel shaped member, co-actingwith the horizontal slit in the web to join one section strip toanother.
